To allwhom it may OGflOfiWM" ii a Be it known that I, HENRY Woos'rnh Far RICK, a citizen of: the United States of America, residing at Mansfield; in the county of Richland and State of Ohio, have invented certain new anduseful Improvements in Combined Gaseous Fuel and VVater-Vapor Burning Heating Apparatus, of which the followingis a speeificationu This invention relates to heating agape-1 ratus and more particularly toan improved form of heating apparatus having a more efficient burner which is at the sametime adapted to supply sufficient moisturetoi the surrounding air to keep the humidity thereof at any predetermined point. 1

The object of the invention is to provide a form of heating apparatus havingmeans associated with the burner thereof foeflashing a predetermined amount of Water into superheated steam and passing such superheated steaminto the combustion zone of the burner in such manner that the heat of combustion Willbe increasedand at the same time asubstantial quantity of moisture passed into thesurrounding air toniaintam any desired degree of humidity thereof;

-It is aavell known factthat wheredt rect heat is employed, as for instance, a gas stove; the humidity of the sunrounkli ng air isgre'atly decreased- *In asmuieh "a humidity of a about sixty insures the most salutary conditions for human 1 beings it is obvious that anything tending to lower that degree of humidity isdeleterious to human health; Recognizing this defect in the Qlfidl nary forms of heating apparatus inmoninion use I devised theapparatus forming the subject matter of this invention. a Not only does my improved apparatus in.- sure the desired degreefofhurhiditytbut I have foundit also muohmore eflicient than any other known to me in that it generates trated and described my invention in sea nection with agas stove having a conven tionai rose burner therein. This, however, is merely ion-descriptivepurposes and it is obvious that myinvention is by nomeans limited to the specific application herein illustrated but that it may be advantageously used in any heating apparatus reef the fuel used; I a a i In the drawing; invvliiolr like characters o'treference designate like parts throughout theseveral views thereon" T 1 a a Figure luis a front eievation of an ordinary type of stove or: heating apparatus showing theinvention applied theretoand the approximate location of an ordinary rose gaseous burlier with respect thereto, 'Fig; Elie a sideelevation oflTigm 1.

In thehdrawingsgreferenoe numeral 1 represents the legs at conventional type of stove" or heating: apparatus; 21 theeasing: and 3 the top thereoft: A blraekett l is bolted; or otherwise fastened within the oasingof the stove preferably; extending across the en tirelvvidth iofthe casing asolearlyisliovvn in Fig. A hollow v'aporiaer 6 preferably formed cone shape is attached at its apex tie the bracket the a bolt 7 Whiohrsuspehds the vaporizerl therefrom; Threaded i aper- 1 three: 8* atnd 9 areprovidedi in the; vaporizer adjacent to the apex thereof and are preferably looat'ed opposite a each other both being in communication with the chamber 10 of the vaporizer.

Hoodslfi 17 are fastened tothe vaporizer and arranged to' partially'extend oiver t-hesteam pipes withthe open portions disposed toward'the vaporizer to permit circulation of the heated products of combustionaround the steam An opening 18 which communicates with the chamber 10 is provided in the'vaporizer' and preferably located in closeproximity to the bottom thereof. A casing 19 which is Y provided with an annular flange- 20 is fastened to the. exteriorof the .vaporizer at one end by the bolts; 21 or any. other well known fastening means; -An asbestos washer 22 is preferably interposed between the faeeof said flange andthe exterior of the .vaporizer as shown in Fig. 4. r

A Water supply Stankv 23 is preferably fastened to the back portion of the casing of the stove by any well known means, and it is equipped with a conventional type of cover the valve in a vertical position. r

2 1; A nipple 25 is -threadably engaged with aisuitable threaded aperture provided in the water tank adjacent to thebottom thereof, and. axneedle 'or other valve 26 which is adapted to permit a'pre-determined amount of water to flow therethrough is preferably connected to *the threaded free end of the nipple so as to leave-the threaded outlet of bestos packing 29-is-fitted Withinthe casing 19 tov surround the feed Water pipe 27. The bottom 15 of the vaporizer is provided with a deflector or baffle rib 30 to deflect or baflle the steam from flowing out of the ends of the steam pipes ands-across the. bottom: of the vaporizer, I The baffle or deflector rib serves toObstruet the flow ofsteam thereby forcing it to back upand tospread-over a larger area of' the bottom of the vaporizer than it WouId-ifia bafljle'or deflecting rib was not used. 11 v v a f onventional type of rose burner 3021s sup'pliedi with :gaseous fuel through" a pipe 7 31' having an air mixer 32. ':The burner is used for the'purpose ofheating the vapors iz'erv6. In theuse or operation of the heating apparatus orstoveto accomplish the objects herein described for the purpose in- V I tended, Water isconductedfrom -any source of. supply tothe valve 26 andpasses through the :valve, The quantity of water passing through said -valve;..is'regulated to permit a'predetermined amount'o'f' water to pass through the valve'into' the 'feed'pipe 27 and from the" end 28 which is-in communication with the chamber 10 :of the vaporizer. As

; the waterdrops from the'end 28 of the feed pipe on the-bottomlfi' ofthe vaporizer, it is instantly flashed into steam or vapor and as the steam rises up in the heated chamber it 'is super-heated. The super-heated steam then passes into the steam pipes, escaping from the ends thereof at points preferably located opposite each other underneath the bottom of the vaporizer thereby mixing with or passing in close proximity to the flame of the gaseous burner durlng co1nbust1on of the gaseous fuel.

I have found that when superheated steam is fed into the combustion zone a distinct secondarycombustion zone is set up above the primary combustion zone with an accompanyingincrease in the heat of combustion,,aconsiderably greater heating effeet being secured from a stove equipped with this form of vaporizer than from the same stove without the vaporizer. Apparentlythere isa decomposition of part of the superheated steam upon contact with the highly heated metal of the vaporizer, the decomposition products then taking part in the combustion, or rather in a secondary combustion, to increase the intensity of the heat evolved. The undecomposed steam, added to that generated during the combustion of the fuel, passes off into the surrounding air to maintain the humidity thereof at the desired point. Obviously the amount of moisture thus added to the atmosphere may be varied at will by varying the quantity of water passed into the vaporizer through the pipe 27 The hoods l6 and 17 tend to catch the combustion products from the gaseous fuel burner permitting their circulation around the-steam pipes to further super-heat the steam passing through the steam pipes. The packing29 is for the purpose of insulating the feed pipe from the heat of the vaporizer to prevent thewater from being vaporized before it is dropped or deposited upon the bottom of the vaporizer.
